gcc/ChangeLog:
2016-09-21 Kugan Vivekanandarajah <kuganv@linaro.org>
* doc/invoke.texi: Document -fdump-tree-evrp.

* tree-vrp.c (extract_range_for_var_from_comparison_expr): New.
(extract_range_from_assert): Factor out
extract_range_for_var_from_comparison_expr.
(vrp_initialize_lattice): New.
(vrp_initialize): Factor out vrp_initialize_lattice.
(vrp_valueize): Fix it to reject complex value ranges.
(vrp_free_lattice): New.
(evrp_dom_walker::before_dom_children): Likewise.

gcc/testsuite/ChangeLog:
2016-09-21 Kugan Vivekanandarajah <kuganv@linaro.org>
* g++.dg/tree-ssa/pr31146-2.C: Run with -fno-tree-evrp as evrp also
does the same transformation.
* g++.dg/warn/pr33738.C: XFAIL as optimization now happens in ccp.
* gcc.dg/tree-ssa/evrp1.c: New test.
* gcc.dg/tree-ssa/evrp2.c: New test.
* gcc.dg/tree-ssa/evrp3.c: New test.
* gcc.dg/tree-ssa/pr20657.c: Check for the pattern in evrp dump.
* gcc.dg/tree-ssa/pr22117.c: Likewise.
* gcc.dg/tree-ssa/pr61839_2.c: Likewise.
* gcc.dg/tree-ssa/pr64130.c: Likewise.
* gcc.dg/tree-ssa/pr37508.c: Change the pattern to be checked as
foling now happens early.
* gcc.dg/tree-ssa/vrp04.c: Likewise.
* gcc.dg/tree-ssa/vrp06.c: Likewise.
* gcc.dg/tree-ssa/vrp16.c: Likewise.
* gcc.dg/tree-ssa/vrp25.c: Likewise.
* gcc.dg/tree-ssa/vrp67.c: Likewise.
